The specific embodiment
Describe the present invention below with reference to accompanying drawings in detail, example embodiment of the present invention has been shown in the accompanying drawing.
Fig. 2 is the schematic diagram that expression comprises the printer of the described detection of an embodiment of the invention trimming device.With reference to Fig. 2, this printer comprises platen 11, make paper P after the intake roller 12a of print zone feeding and 12b, print processing are finished, paper is discharged printer exit roller 14a and 14b, have print cartridge and ink be sprayed onto on the paper P by nozzle, with the printhead 13 of carrying out print processing, be installed in a side of printhead 13 and when detect paper P, export transducing signal to level sensor (alignment sensor) 15.This is to level sensor 15 optical pickocff preferably, and it is radiated at light on the paper P, and will be converted to the signal of telecommunication from the light quantity of paper P reflection.This preferably is installed in the front end of printhead 13 along the direction (after this being called paper feed direction) of paper P feeding to level sensor 15.Black material is formed on the whole surface of detection zone 16.This black material absorbs light, makes this detection zone 16 obviously be different from the paper P of reflection ray.
This printer also comprises analogue-to-digital converters (ADC) 17, detector 18 and controller 19, wherein, these analogue-to-digital converters (ADC) 17 will be data signal from the analog signal conversion that level sensor 15 is received, this detector 18 is by handling the edge that detects paper P from the data signal of ADC17 output, and this controller 19 makes the edge of detected paper P align with the nozzle (not shown) that is positioned at printhead 13 ends.This controller 19 transmits control signal and controls level sensor 15, and then drives printhead 13, control intake roller 12a and 12b, and control exit roller 14a and 14b.
Detect the edge of paper P in the following manner.Controller 19 makes paper P enter print zone by driving intake roller 12a and 12b.When paper P printhead 13 times when print zone advances, controller 19 calculates the distance that paper P advances according to the driving signal of intake roller 12a and 12b.When definite paper P enough big distance of having advanced, make its front end be positioned under the level sensor 15, this is mapped on the paper P illumination to level sensor 15 every 1ms.What be attached to printhead 13 front ends paper P on detected required information by light is radiated to level sensor 15 before print processing begins.
When making paper when paper feed direction is advanced, controller 19 is by means of the leading section that level sensor 15 is scanned paper P.Early stage in scan process, very little to level sensor 15 detected light quantities, but along with paper P covers more detection zone 16 and increases gradually.Along with the terminal part of paper P leaves detection zone 16, detection zone 16 is not covered by paper P gradually, therefore, level sensor 15 detected light quantities is reduced gradually.
If detector 18 detects the front end of paper P, then controller 19 makes the front end of detected paper P align with the nozzle that is positioned at printhead 13 front ends, and feed-disabling paper P.
Fig. 3 A represents to begin time lapse till the time of feed-disabling paper P the process, the example of the variation of the mode of operation of each intake roller 12a and 12b from the time of feeding paper P.Fig. 3 B represents an example to the output signal of level sensor 15.Fig. 3 C represents an example of the output signal of detector 18.With reference to Fig. 3 B, when level sensor 15 is radiated at the leading section of paper P with light, the light signal strength of level sensor 15 is increased in time, form for example sine curve.Detector 18 calculates the variation of output signals width (being gradient) to level sensor 15, and has an edge that a bit comes to determine paper P of greatest gradient by detection.When level sensor 15 is radiated at the terminal part of paper P with light, the intensity of the output signal of level sensor 15 is weakened, form for example arcsine curve.
Fig. 4 represents the flow chart of trimming rim detection and print processing according to an embodiment of the invention.With reference to Fig. 4, in step 400, feeding also transmits paper P.In step 401, optical pickocff, or to level sensor 15 every 1ms run-down paper P.If the result in the scan process of step 402 is the front end that detects paper P, then feeding paper P aligns with the nozzle that is positioned at printhead 13 ends up to the front end of paper P in step 403.Then in step 404, this printhead 13 to carrying out print processing terminally, and does not stay any margin from front end on whole four limits of paper P on paper P.
Fig. 5 is the detail flowchart of the processing at every 1ms of expression example embodiment according to the present invention edge that detects a paper.With reference to Fig. 5, in step 500, detector 18 detects minimum of a value from the numerical value of ADC 17 outputs.In step 502, if do not detect minimum of a value from the numerical value of ADC 17 outputs, then detector 18 is set or definite minimum of a value from the numerical value of ADC 17 outputs.When not having detected paper, then obtain this minimum of a value.Detector 18 is set ADC 17 mean value of n value of output continuously, as this minimum of a value.When paper P perk (tilt) or do not drive reposefully to level sensor 15 during attached printhead 13, the light quantity that level sensor 15 is received can change in preset range.Therefore, the output of level sensor 15 and the output of ADC 17 are changed in preset range.So detector 18 must be that a minimum of a value is set in the output of ADC 17 as described above.
If detect this minimum of a value from the output valve of ADC 17 in step 500, then detector 18 is checked the edge that whether has detected paper P in step 503.If detected the limit of paper P, detector 18 end process then.Otherwise detector 18 reads the current output valve of ADC 17 in step 504.In step 505, detector 18 deducts detected minimum of a value in step 500 from the current output valve of ADC 17.After this, result that detector 18 relatively deducts in step 506 (hereinafter being called current (Δ) value) and previous Δ value.In step 507, if previous Δ value more than or equal to former Δ value, then detector 18 makes the numerical value of counter add 1.Δ value formerly is during greater than former Δ value, judges that the gradient that the output of ADC 17 changes increases, and shown in Fig. 3 B, paper P enters detection zone 16 under to level sensor 15.
As judging in the step 508 like that, if after the step 507, new counter values is greater than predetermined value, for example 3, then in step 509 with the current previous Δ value of Δ value replacement.This moment, detect the current location of paper P front end, and in step 509, testing result saved as parameter POS.Herein, predetermined value promptly 3 is determined by experiment.Specifically, if the gradient of waveform shown in Fig. 3 B increases 3 times continuously, then judge to have reached its substantial maximum, and judge the edge that detects paper P.If the numerical value of counter is not more than 3 in step 508, then finishes dealing with and finish.
If Δ value current in step 506 is less than previous Δ value, and if in step 510 numerical value of counter in step 512 determine then that greater than 3 the target location be " POS+ apart from ".Herein, " distance " refers to level sensor 15 and the distance between the nozzle of printhead 13 front ends.Specifically, when the front end of paper P alignd with the nozzle that is positioned at printhead 13 front ends, this target location was the position of paper P.
If the numerical value of counter is less than 3 in step 510, then the waveform shown in the process decision chart 3B has been subjected to The noise, and counter values and parameter POS are made zero, thereby finishes and end process.
